I'm trying to implement an auto update for the user who creates a record using ModelAdmin save_model as described here. I wasn't able to work out how to get around the kwarg error "save() got an unexpected keyword argument 'force_insert'".
admin.py
from myapp.myproj.models import Activity
from django.contrib import admin
class ActivityAdmin(admin.ModelAdmin):
exclude = ('cruser',)
list_display = ('activity_nm', 'activity_desc', 'startdt', 'enddt','upddt','crdt')
def save_model(self, request, obj, form, change):
if not change:
obj.cruser = request.user
obj.save()
admin.site.register(Activity, ActivityAdmin)
The documentation states that
"The save_model method is given the HttpRequest, a model instance, a ModelForm instance and a boolean value based on whether it is adding or changing the object."
Is this something automatic or do I need to pass it in from the view? If that's not the issue, then what else could it be?
EDIT: changed code back to match example.
update
If you have overridden save()
method of Activity
or some other Models that get saved in meanwhile, but forgotten to accept force_insert
as keyword argument, this error could happen:
def save(self):
...
# should be
def save(self, force_insert=False, force_update=False, using=None):
...
# or at least
def save(self, **kwargs):
...
Check the trackback to locate the failed save
Your code does not fully follow the code from b-list.org, try:
def save_model(self, request, obj, form, change):
if not change:
obj.cruser = request.user
obj.save()
